The 2nd Sqn of the 2nd Wing will be the first to receive Mirage. Following the restructuring due to the arrival of the Mirage, 1st and 8th Sqn will be transferred to 3rd Wing in Bierset late 1970 where they will receive their first Mirage 5 BA and BD. In September 1970, the 42nd Sqn, moved to Florennes, receives the first Mirage 5 BR.
None Mirage 5 was equipped with radar, but they all wore on the back of a stick stop. The BA had received a strong tapered nose bearing at its peak a pitot probe The BR were a few similar equipements like at the Mirage III R . This was also the case for BD with IIIBE Mirage.

At the end of 1980, Mirage were equipped with a new Ejection Martin Baker Mk 10 seat (zero-zero) as a replacement for Martin Baker 4.
In August 1989, the the Air Force Staff decide of the modernization MIRSIP (MIRage System Improvement Program) of a number of Mirage BA and BD by adding duck surfaces at the front, the modernisation of Navigation calculator, a wiring for the carriage of a pod of recognition and a unique system of supply under pressure for all tanks (internal and external). These modernized aircraft were able to fly until 2005 or even 2010 according to some sources. At the Time of the 1st Gulf War , the 18 Mirage of the 3rd Wing were deployed in Diyarbakir (Turkey) from January 3rd to March 12th 1991 to participate in the Operation Ace Guard. The Mirage made 606 operational missions and 816 flying hours. Shortly after the return to Belgium of its aircraft, 8th Sqn is dissolved.
Initially all Mirage 5 wore camo type Vietnam (above beige, light green and olive green and grey clear below). In 1981, the underside of the aircraft was filled yet operational camouflage type Vietnam (called full camouflage), which, in turn, made it less visible Mirage often used for missions at low altitudes.
The 1st Sqn/3rd Wing and 2nd Sqn/2nd Wing retain their Mirage until the late 1980's. The 8th Sqn/3rd Wing in Bierset was dissolved in September 1991. The 42nd Sqn, last unit to fly Mirage in Belgium, after 23 years of use of its QB, will be dissolved, in turn, on December 19th 1993 as a result of budget cuts.
The 15 BA and 5 BD modernized, with the exception of test flights, not ever served in Belgium always following the budget cuts that occurred in 1992 and 1993. They will be stored at Koksijde until 1994. At that time the 20 Mirage MIRSIP and 4 BR 1 BD and not upgraded will be sold to Chile through the SABCA (Société Anonyme Belge de Construction Aerospace). These BD and BR serve as a reserve of spare parts.
Here is a table showing of 25 aircraft ex FAé sold in Chile and returned to service currently under the name of Elkan. These aircraft were withdrawn from service on December 26th 2006

No information is available on the denomination of Mirage 5 and Mirage III. The only plausible explanation is the need to differentiate Belgian Mirage V who are different. Currently, in the literature dealing upon Belgian Mirage appellations 5 and V are used with the confusion that can result. If you see "Mirage" Drivers in the series "Patrick Baudry present - Editions Atlas, 1991," you will find a photo of the prototype Mirage V bearing the designation Mirage M5 under the canopy and in the text reference is made to Mirage 5 (and this is not the Belgian Mirage).
My article does not pretend to be complete and without error.
The picture of BR-27 shows the aircraft, equipped with external tanks 3.
None feature improved Mirage 5 MIRSIP have been found. You will find on Internet sites providing different characteristics.

Nota bene:
The Mirage 5 BA BA-03 of Temploux has no longer its reactor, the ejector seat, his viewfinder, its canons, the front part of the shroud of arresting hook (keel), and a shroud of an articulation of flaperons.
The same BA-03 has been repainted but the melted color has not been achieved. Some pictures of this walkaurond were retouched for more realism
